Survivorship, Site Fidelity and Weight Dynamics of Male Hybomitra aurilimba (Diptera: Tabanidae) at a Hilltop Mating Arena
Bibliographic record
Abstract
I present a mark-release-recapture study of individually marked males of the horsefly Hybomitra aurilimba (Stone) (Diptera: Tabanidae) at a hilltop mating arena in southern Ontario, Canada; the study occupied much of the seasonal on-wing period of the males. Survivorship, population size, daily recruitment and site fidelity were examined by recapture of marked males. Flies were often recaptured on the day of marking and thereafter on up to 7 different days, covering periods up to 16 d following marking. The population was small (<100 males) with a relatively high daily recruitment. The males exhibited pronounced and prolonged fidelity to both the overall mating arena and to individual hovering sites within the arena. Mean daily survivorship was relatively high (0.84 ± 0.021 (SEM)), leading to a mean on-site residency time of 5.7 d (95% CL: 4.4–7.9 d). Marked and recaptured males were weighed; they exhibited highly individual patterns of substantial weight losses and gains, both within and among days.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
